Abstract

Abstract: In this paper, the time-fractional coupled viscous Burgers' equation (CVBE) and Drinfeld-Sokolov-Wilson equation (DSWE) are solved by the Sawi transform coupled homotopy perturbation method (HPM). The approximate series solutions to these two equations are obtained. Meanwhile, the absolute error between the approximate solution given in this paper and the exact solution given in the literature is analyzed. By comparison of the graphs of the function when the fractional order $\alpha$ takes different values, the properties of the equations are given as a conclusion.

Key words: Caputo fractional derivative, coupled viscous Burgers' equation (CVBE), Drinfeld-Sokolov-Wilson equation (DSWE), Sawi transform, homotopy perturbation method (HPM)
